Modular equipment rack system for data center

ABSTRACT

Various technologies described herein pertain to racking equipment in a data center. A modular equipment rack system can include an upper track, a lower track, a vertical support, a power and network distribution unit, and a tray. The upper track and the lower track can respectively include incrementally spaced mounting locations at which the vertical support and the power and network distribution unit can be attachable. The tray can be attachable to the vertical support and the power and network distribution unit when the vertical support is attached to the upper track at a first upper mounting location and attached to the lower track at a corresponding first lower mounting location, and the power and network distribution unit is attached to the upper track at a second upper mounting location and attached to the lower track at a corresponding second lower mounting location.

BACKGROUND

A data center is a facility that houses computer equipment and relatedcomponents. Data centers oftentimes include many server computers andauxiliary equipment such as, for instance, storage systems, networkinfrastructure equipment, and the like. Equipment is commonlyaccommodated and organized in data centers by being mounted on racks.

Rack mountable equipment for use in a data center is oftentimes designedto fit in conventional, standard equipment racks. Examples of such racksinclude racks that conform to standards such as Electronic IndustriesAlliance (EIA)-310-D, European Telecoms Standards Institute (ETSI), andso forth. Accordingly, configurations of rack mountable equipmentcommonly are limited by the configuration of the rack in which suchequipment can be mounted. For example, a 19-inch rack that conforms toEIA-310-D can include a standardized frame or enclosure for mountingequipment that is approximately 17.75 inches wide. The equipmenttypically has a front panel that is approximately 19 inches wide withedges or ears that protrude in the width direction on each side suchthat the edges or ears allow the equipment to be fastened to the rack(e.g., with screws, clips, bolts, etc.). Pursuant to this example, theheight of the equipment that is mountable in the 19-inch rack iscommonly standardized to be a multiple of 1.75 inches (e.g., a rackunit).

Moreover, configuration of the equipment can be dependent on anapplication being run with the equipment. Accordingly, differentequipment configurations with differing volumetric requirements can beused within a conventional data center. To accommodate the differingvolumetric requirements for the different equipment configurations,disparate systems that fit within conventional, standard equipment racksoftentimes are employed, which can cause increased supply chaincomplexity.

Further, when servers are refreshed (e.g., after a few years of use),other equipment such as power supplies, fans, sheet metal, connectors,batteries, etc. is oftentimes replaced as a result of being part of theinfrastructure installed in a rack with the servers or a container inwhich the servers are included. For instance, a typical blade system caninclude a chassis that mounts into a conventional, standard equipmentrack. The chassis can include slides or housings into which a pluralityof blades (e.g., servers) can be inserted. However, the chassis of atypical blade system oftentimes is able to couple with blades having afixed size. Moreover, blades for a chassis of a particular manufacturercommonly differ in size from blades for a chassis of a differentmanufacturer. Thus, if the blades are refreshed (e.g., when upgradingafter a few years, etc.), then the chassis commonly is unable to bereused and oftentimes replaced.

SUMMARY

Described herein are various technologies that pertain to rackingequipment in a data center. A modular equipment rack system for a datacenter can include an upper track, a lower track, a vertical support, apower and network distribution unit, and a tray. The upper track caninclude upper mounting locations incrementally spaced along a length ofthe upper track, and the lower track can include lower mountinglocations incrementally spaced along a length of the lower track.Further, the vertical support and the power and network distributionunit can be attachable to the upper track at the upper mountinglocations and attachable to the lower track at the lower mountinglocations.

DETAILED DESCRIPTION

Various technologies pertaining to racking equipment in a data centerare now described with reference to the drawings, wherein like referencenumerals are used to refer to like elements throughout. In the followingdescription, for purposes of explanation, numerous specific details areset forth in order to provide a thorough understanding of one or moreaspects. It may be evident, however, that such aspect(s) may bepracticed without these specific details. In other instances, well-knownstructures and devices are shown in block diagram form in order tofacilitate describing one or more aspects. Further, it is to beunderstood that functionality that is described as being carried out bycertain system components may be performed by multiple components.Similarly, for instance, a component may be configured to performfunctionality that is described as being carried out by multiplecomponents.

Moreover, the term “or” is intended to mean an inclusive “or” ratherthan an exclusive “or.” That is, unless specified otherwise, or clearfrom the context, the phrase “X employs A or B” is intended to mean anyof the natural inclusive permutations. That is, the phrase “X employs Aor B” is satisfied by any of the following instances: X employs A; Xemploys B; or X employs both A and B. In addition, the articles “a” and“an” as used in this application and the appended claims shouldgenerally be construed to mean “one or more” unless specified otherwiseor clear from the context to be directed to a singular form.

As set forth herein, a modular equipment rack system for a data centercan simplify upgrading or refreshing equipment mounted within such asystem. The modular equipment rack system can be an adjustable supportstructure that can provide configuration flexibility, thereby mitigatesize constraints of equipment that can be mounted within the systemoftentimes associated with conventional, standard equipment racks whileallowing for reconfiguration. For instance, components of the modularequipment rack system can be reused and/or reconfigured when equipmentmounted within the system is upgraded or refreshed.

As described herein, the modular equipment rack system can include apower and network distribution unit and a support member (e.g., verticalsupport, guide module, etc.) that can be located at a distance from eachother. The distance can be changed to accommodate various sizes oftrays, where a tray can include server(s), storage device(s), acombination thereof, etc. Thus, if a size of tray(s) is changed whenupgrading or refreshing servers, storage devices, etc., then thedistance between the power and network distribution unit and the supportmember can be altered, thereby allowing for reuse of such components.Further, the modular equipment rack system can support a configurationwhere more than one tray size is employed.

Referring now to the drawings, FIG. 1 illustrates an isometric view ofan exemplary modular equipment rack system 100 for a data center. Themodular equipment rack system 100 includes an upper track 102 and alower track 104. The upper track 102 includes upper mounting locationsincrementally spaced along a length of the upper track 102. Similarly,the lower track 104 includes lower mounting locations incrementallyspaced along a length of the lower track 104.

Moreover, the modular equipment rack system 100 can include one or morevertical supports. As shown in the depicted example of FIG. 1, themodular equipment rack system 100 includes four vertical supports:vertical support 106, vertical support 108, vertical support 110, andvertical support 112 (collectively referred to as vertical supports106-112). It is to be appreciated, however, that the modular equipmentrack system 100 can include substantially any number of verticalsupports and is not limited to including the four vertical supports106-112 illustrated in FIG. 1.

The vertical supports 106-112 are attachable to the upper track 102 andthe lower track 104. The vertical supports 106-112 are attachable to theupper track 102 at the upper mounting locations. Further, the verticalsupports 106-112 are attachable to the lower track 104 at the lowermounting locations. Thus, top ends of the vertical supports 106-112 arecapable of being fastened, secured, joined, etc. to the upper track 102at any of the upper mounting locations of the upper track 102, andbottom ends of the vertical supports 106-112 are capable of beingfastened, secured, joined, etc. to the lower track 104 at any of thelower mounting locations of the lower track 104.

The modular equipment rack system 100 can further include one or morepower and network distribution units. The example illustrated in FIG. 1shows the modular equipment rack system 100 including two power andnetwork distribution units: power and network distribution unit 114 andpower and network distribution unit 116 (collectively referred to aspower and network distribution units 114-116). Moreover, it iscontemplated that the modular equipment rack system 100 can includesubstantially any number of network and power distribution units and isnot limited to including the two network and power distribution units114-116 depicted in FIG. 1.

Similar to the vertical supports 106-112, the power and networkdistribution units 114-116 are attachable to the upper track 102 and thelower track 104. The power and network distribution units 114-116 areattachable to the upper track 102 at the upper mounting locations.Moreover, the power and network distribution units 114-116 areattachable to the lower track 104 at the lower mounting locations.Accordingly, top ends of the power and network distribution units114-116 are capable of being fastened, secured, joined, etc. to theupper track 102 at any of the upper mounting locations of the uppertrack 102, and bottom ends of the power and network distribution units114-116 are capable of being fastened, secured, joined, etc. to thelower track 104 at any of the lower mounting locations of the lowertrack 104.

According to an example, the upper track 102 can be installed on aceiling of a data center and the lower track 104 can be installed on afloor of the data center. By way of another example, it is contemplatedthat the upper track 102 can be a floating member and the lower track104 can be installed on the floor of the data center. Following thisexample, the lower track 104 can be installed on the floor of the datacenter, bottom end(s) of one or more of the vertical supports 106-112and/or one or more of the network and power distribution units 114-116can be attached to the lower track 104, and thereafter the upper track102 can be attached to top end(s) of the one or more of the verticalsupports 106-112 and/or the one or more of the network and powerdistribution units 114-116 attached to the lower track 104. Additionallyor alternatively, top end(s) of one or more of the vertical supports106-112 and/or one or more of the network and distribution units 114-116can be attached to the upper track 102, and thereafter bottom end(s) ofthe one or more of the vertical supports 106-112 and/or the one or moreof the network and power distribution units 114-116 attached to theupper track 102 can be attached to the lower track 104. It is to beappreciated, however, that the claimed subject matter is not limited tothe foregoing illustrations.

Further, the upper track 102 and the lower track 104 can accept mountingof the vertical supports 106-112 or the network and power distributionunits 114-116 at a standard increment. By way of example, the standardincrement can be approximately one inch. Following this example, uppermounting locations of the upper track 102 can be spaced at an incrementof substantially one inch along the length of the upper rack 102 andlower mounting locations of the lower track 104 can be spaced at anincrement of substantially one inch along the length of the lower track104. Yet, it is contemplated that the upper mounting locations and thelower mounting locations can be spaced at an increment other thanapproximately one inch.

As depicted in FIG. 1, the vertical support 106 (e.g., a top end of thevertical support 106) is attached to the upper track 102 at a firstupper mounting location. The vertical support 106 (e.g., a bottom end ofthe vertical support 106) is also attached to the lower track 104 at afirst lower mounting location, where the first lower mounting locationcorresponds with the first upper mounting location (e.g., the firstlower mounting location and the first upper mounting location arealigned). Moreover, the power and network distribution unit 114 (e.g., atop end of the power and network distribution unit 114) is attached tothe upper track 102 at a second upper mounting location. The power andnetwork distribution unit 114 (e.g., a bottom end of the power andnetwork distribution unit 114) is attached to the lower track 104 at asecond lower mounting location. Further, the second lower mountinglocation corresponds with the second upper mounting location (e.g., thesecond lower mounting location and the second upper mounting locationare aligned).

Moreover, one or more trays (e.g., a tray 118, etc.) can be attachableto the vertical support 106 and the power and network distribution unit114, which are attached to the upper track 102 and the lower track 104as illustrated in FIG. 1. A tray can include server(s), storagedevice(s), a combination thereof, and the like. Further, a tray caninclude a connector suitable for blind mating at a rear of the tray,where the connector can interconnect with a power and networkdistribution unit. According to an illustration, a tray can include ablind mate connector that couples with the power and networkdistribution unit 114 when the tray is attached to the vertical support106 and the power and network distribution unit 114.

The modular equipment rack system 100, as configured in FIG. 1, supportstrays of different widths. Accordingly, trays that include differentserver configurations, numbers of storage devices, etc. can be used withthe modular equipment rack system 100. More particularly, the verticalsupports 106-112 and the power and network distribution units 114-116can be attached at different mounting locations (or pitches) on themounting tracks (e.g., the upper track 102 and the lower track 104) toaccommodate variation in tray dimensions. Further, in a given column(e.g., between the vertical support 106 and the power and networkdistribution unit 114, etc.), the trays can have substantially similarwidths. However, trays in different columns can have different widths.In accordance with the depicted example, narrow trays can be attachablebetween the vertical support 106 and the power and network distributionunit 114, narrow trays can be attachable between the power and networkdistribution unit 114 and the vertical support 108, wide trays can beattachable between the vertical support 108 and the power and networkdistribution unit 116, and wide trays can be attachable between thepower and network distribution unit 114 and the vertical support 110.Moreover, the vertical support 110 and the vertical support 112 can bepositioned within the modular equipment rack system 100 to supportstandard equipment (e.g., configured as a standard 19-inch rack portionwithin the modular equipment rack system 100). Yet, it is to beappreciated that the claimed subject matter is not so limited.

Moreover, the modular equipment rack system 100 can be reconfigurable.Accordingly, the vertical supports 106-112 and the power and networkdistribution units 114-116 can be slidable on the upper track 102 andthe lower track 104. For instance, the upper track 102 and the lowertrack 104 can be substantially similar to seat tracks in an airplane;yet, the claimed subject matter is not so limited. Additionally oralternatively, vertical support(s) and/or power and network distributionunit(s) can be added to or removed from the modular equipment racksystem 100 during reconfiguration.

By way of example, a first tray (e.g., the tray 118, etc.) having afirst width can be attachable to the vertical support 106 and the powerand network distribution unit 114 when positioned as shown in FIG. 1.Following this example, when refreshing equipment (e.g., upgrading aserver attached to the first tray), the vertical support 106 and/or thepower and network distribution unit 114 can be slid along the uppertrack 102 and the lower track 104 to be separated at a distance suitablefor attaching to a second tray having a second width. The second width,for instance, can be wider or narrower than the first width. Accordingto an illustration, the second tray with a different width compared tothe first tray can be attachable to the vertical support 106 and thepower and network distribution unit 114 when the vertical support 106 isattached to the upper track at a third upper mounting location andattached to the lower track at a third lower mounting location thatcorresponds with the third upper mounting location, where the first andthird upper mounting locations differ and the first and third lowermounting locations differ. Additionally or alternatively, the secondtray can be attachable to the vertical support 106 and the power andnetwork distribution unit 114 when the power and network distributionunit 114 is attached to the upper track at a fourth upper mountinglocation and attached to the lower track at a fourth lower mountinglocation that corresponds with the fourth upper mounting location, wherethe second and fourth upper mounting locations differ and the second andfourth lower mounting locations differ. It is to be appreciated,however, that that claimed subject matter is not limited to theforegoing example.

Now turning to FIG. 2, illustrated is an isometric view of an exemplarypower and network distribution unit 200 (e.g., one of the power andnetwork distribution units 114-116 of FIG. 1). The power and networkdistribution unit 200 supplies power and networking to tray(s) (e.g.,the tray 118 of FIG. 1, etc.) when the tray(s) are attached thereto.According to the illustrated example of FIG. 2, the power and networkdistribution unit 200 can include a power unit that supplies power toone or more electronic assemblies (e.g., the trays). However, inaccordance with another example (not shown), the power and networkdistribution unit 200 can couple with a power unit that supplies powerto the one or more electronic assemblies.

The power unit can convert alternating current (AC) voltage (e.g., 115VAC to 480 VAC) to a distribution voltage (e.g., 12 VDC to 400 VDC) usedto run associated electronics. Moreover, the power unit can providepower smoothing. The power unit included in and/or coupled with thepower and network distribution unit 200 can include one or more powersupplies. For instance, the power unit can include a plurality of powersupplies that are coupled together to supply power while providingredundancy (e.g., in the event of failure of one or more power supply).According to the depicted example of FIG. 2, the power and networkdistribution unit 200 can include four power supplies (e.g., the powerunit): a power supply 202, a power supply 204, a power supply 206, and apower supply 208 (collectively referred to as power supplies 202-208);however, it is to be appreciated that the claimed subject matter is notlimited to the example shown in FIG. 2. Moreover, the power unit caninclude a connection point (not shown) for joining to other powerunit(s) (e.g., included in or coupled with disparate power and networkdistribution unit(s)) to provide power redundancy in the event of powersupply failure.

Moreover, the power supplies 202-208 can provide local energy storage(LES) functionality in the event of a utility power failure.Additionally or alternatively, the power supplies 202-208 can beconnected to a LES (not shown) to provide LES functionality. Forinstance, the LES can be connected to a connection point that adds theLES to output of the power supplies 202-208; yet, the claimed subjectmatter is not so limited.

Further, a power and network distribution unit can include one or morenetwork switches. In the example depicted in FIG. 2, the power andnetwork distribution unit 200 includes two network switches: a networkswitch 210 and a network switch 212 (collectively referred to as networkswitches 210-212). The network switches 210-212 in the power and networkdistribution unit 200 can be replaceable and/or upgradable.

Moreover, the power and network distribution unit 200 can include abackplane 214 that includes tray connection points that are respectivelyconnectable with blind mate connectors of trays. The backplane 214 candistribute power from the power unit (e.g., the power supplies 202-208)to tray(s) connected therewith via the tray connection points.Additionally or alternatively, the backplane 214 can provide the networkswitches 210-212 with network distribution to the tray(s) connectedtherewith via the tray connection points. Hence, the network switches210-212 can connect with the backplane 214, which can directly connectwith the tray(s), thereby mitigating use of cables from the networkswitches 210-212 to the tray(s). However, according to other examples,it is to be appreciated that the network switches 210-212 can beconnected to the tray(s) via cables.

The power and network distribution unit 200 can also supply controlsignals to tray(s) connected therewith via the tray connection points.The power and network distribution unit 200 can include a rack level orchassis level controller (not shown), for example. Such controller canmonitor systems attached to the power and network distribution unit 200and/or provide a control interface to the systems attached to the powerand network distribution unit 200. Accordingly, the power and networkdistribution unit 200 can support signaling for system control and/orerror monitoring.

The power and network distribution unit 200 can also include a supportstructure that is attachable to an upper track (e.g., the upper track102 of FIG. 1) and a lower track (e.g., the lower track 104 of FIG. 1).In the depicted example of FIG. 2, the support structure of the powerand network distribution unit 200 can include four vertical rails: avertical rail 216, a vertical rail 218, a vertical rail 220, and avertical rail 222 (collectively referred to as vertical rails 216-222).The vertical rails 216-222 can each be attached to the power supplies202-208, the network switches 210-212, the backplane 214, or arespective subset thereof. According to an example, the vertical rail216 and the vertical rail 220 can be attached to the power supplies202-208 and the network switches 210-212, and the vertical rail 218 andthe vertical rail 222 can be attached to the power supplies 202-208;however, it is to be appreciated that the claimed subject matter is notso limited.

Moreover, the power and network distribution unit 200 includes verticalmounting locations incrementally spaced along a height of the power andnetwork distribution unit 200. For instance, the support structure(e.g., the vertical rails 216-222) can include vertical mountinglocations. According to an example, the vertical mounting locations canbe spaced at an increment of substantially 1.75 inches (e.g., a rackunit) along the vertical rails 216-222 in the height direction. However,it is contemplated that the spacing between the vertical mountinglocations along the height of the power and network distribution unit200 can be substantially any other increment, and is not limited tobeing approximately 1.75 inches.

Tray(s) are attachable to the vertical mounting locations of the powerand network distribution unit 200. Moreover, the power and networkdistribution unit 200 can support double-sided mounting (e.g., trays canbe attached to both sides of the power and network distribution unit 200at vertical mounting locations). For example, a first set of trays canbe attached to the vertical rail 216 and the vertical rail 218, and asecond set of trays can be attached to the vertical rail 220 and thevertical rail 222.

According to an example, the power and network distribution unit 200 canbe approximately four inches wide. However, it is to be appreciated thatthe claimed subject matter is not so limited, and any width of the powerand network distribution unit 200 is intended to fall within the scopeof the hereto appended claims.

In accordance with another example, the power and network distributionunit 200 (e.g., the power supplies 202-208, the network switches210-212, LESs, etc.) can have a longer life compared to a server.Accordingly, short life technology components (e.g., attachable to atray) can be separated from longer life technology components. Thus,when short life technology components are upgraded, the longer lifetechnology components need not be replaced (e.g., the power supplies202-208 can be replaced when the technology is obsolete as opposed towhen a server is refreshed since power supply technology tends not tochange as rapidly as server technology). Rather, the longer lifetechnology components can continue to be used after an upgrade of theserver.

Pursuant to another example, the power supplies 202-208 can be commoditycomponents. Following this example, customization of system power withinthe power and network distribution unit 200 can be supported by loadingdifferent wattage power supplies and/or partially populating the powerand network distribution unit 200 with power supplies (e.g., the powerand network distribution unit 200 can include a subset of the powersupplies 202-208). In contrast, if customized power supplies areemployed as opposed to commoditized power supplies, such customizationcan be more expensive. It is to be appreciated, however, that theclaimed subject matter is not limited to the foregoing example.

Now referring to FIG. 3, illustrated is an isometric view of anexemplary vertical support 300 (e.g., one of the vertical supports106-112 of FIG. 1). The vertical support 300 includes two double-sidedvertical rails: a double-sided vertical rail 302 and a double-sidedvertical rail 304 (collectively referred to as double-sided verticalrails 302-304). Moreover, as shown in the example of FIG. 3, thevertical support 300 includes a plurality of cross members attachedbetween the double-sided vertical rails 302-304: a cross member 306, across member 308, a cross member 310, a cross member 312, and a crossmember 314 (collectively referred to as cross members 306-314). Yet, itis to be appreciated that the claimed subject matter is not limited tothe foregoing example.

Further, the vertical support 300 includes vertical mounting locationsincrementally spaced along a height of the vertical support 300. Thedouble-sided vertical rails 302-304 can include the vertical mountinglocations along two sides thereof, where the vertical mounting locationsare incrementally spaced in the height direction. According to anexample, the vertical mounting locations can be spaced at an incrementof substantially 1.75 inches (e.g., a rack unit) along the double-sidedvertical rails 302-304 in the height direction. Yet, it is contemplatedthat the spacing between the vertical mounting locations along theheight of the vertical support 300 can be substantially any otherincrement, and is not limited to being approximately 1.75 inches. By wayof example, a tray can be attached to the vertical support 300 at afirst vertical mounting location on the vertical support 300 andattached to a power and network distribution unit at a correspondingfirst vertical mounting location on the power and network distributionunit.

The vertical support 300 can provide guidance and support for an edge ofa tray. For instance, an edge of a tray can be attached to the verticalsupport 300 and an opposite edge of the tray can be attached to a powerand network distribution unit (e.g., one of the power and networkdistribution units 114-116 of FIG. 1, the power and network distributionunit 200 of FIG. 2, etc.). However, it is also contemplated that theopposite edge of the tray can be attached to a disparate verticalsupport, which can be substantially similar to the vertical support 300.

With reference to FIG. 4, illustrated is a block diagram of an exemplarytray 400. The tray 400 can be substantially any size. Further, the tray400 can be made of metal; however, the claimed subject matter is not solimited.

The tray 400 can be attachable to a power and network distribution unit(e.g., one of the power and network distribution units 114-116 of FIG.1, the power and network distribution unit 200 of FIG. 2, etc.) and avertical support (e.g., one of the vertical supports 106-112 of FIG. 1,the vertical support 300 of FIG. 3, etc.). The tray 400 includes a blindmate connector 402 that couples with the power and network distributionunit when the tray 400 is attached to the power and network distributionunit and the vertical support. For instance, the blind mate connector402 can be at a rear edge of the tray 400. Moreover, the blind mateconnector 402 can be suitable for interconnecting the tray 400 with atray connection point of a backplane, where the power and networkdistribution unit includes the backplane. The blind mate connector 402can reduce an amount of recabling to be performed during an upgrade.

The tray 400 can further include a server 404 and/or a storage device406 (e.g., the server 404 and the storage device 406 can be attached tothe tray 400). According to an example, the tray 400 can include aplurality of servers similar to the server 404. Additionally oralternatively, the tray 400 can include a plurality of storage devicessimilar to the storage device 406. Moreover, the storage device 406 canbe a hard drive (HDD), a solid-state drive (SSD), or the like. It isalso contemplated that the tray 400 can include other components suchas, for instance, a battery (e.g., LES) and so forth. Further, the tray400 can adapt commodity components such as the server 404 and thestorage device 406 to a standard connection (e.g., via the blind mateconnector 402).

In accordance with an example, the blind mate connector 402 can be astandalone module on the tray 400. Following this example, the blindmate connector 402 can convert an interface from the server 404 to aninterface that can interconnect with a power and network distributionunit. By way of another example, the blind mate connector 402 can bepart of the server 404 (e.g., part of a server motherboard).

According to an example, as server technology changes, a size of aserver board oftentimes can become smaller. Thus, if the server 404 isreplaced with an upgraded server having a smaller server board, then theserver 404 can be removed from the tray 400 and the upgraded server canbe attached to the tray 400. Alternatively, the upgraded server can beattached to a disparate tray with a substantially similar size comparedto the tray 400. Accordingly, the tray 400 or the disparate tray withthe substantially similar size can continue to be attachable to thepower and network distribution unit and the vertical support withoutrearrangement.

By way of another example, if the server 404 is replaced with theupgraded server having the smaller server board, then the upgradedserver can be attached to a disparate tray with a smaller size comparedto the tray 400. Following this example, the power and networkdistribution unit and the vertical support can be repositioned withrespect to each other (e.g., moved closer to be separated by a distancesuitable for attaching to the smaller disparate tray), and thereafter,the smaller disparate tray can be attachable to the power and networkdistribution unit and the vertical support. Additionally oralternatively, the smaller disparate tray (e.g., narrower than the tray400, etc.) can be attachable to a different power and networkdistribution unit and/or a different vertical support, which are locatedcloser to each other at a distance suitable for attaching to the smallerdisparate tray.

Further, it is contemplated that the tray 400 can optionally include aninterface board that provides the blind mate connector 402 andadditional functionality that can be used to adapt commodity components(e.g., the server 404, storage device 406, etc.) to the standardconnector. The other functionality, for instance, can be additionalpower conversion to supply additional voltages to the server 404 (e.g.,a voltage other than a standard voltage supplied by the power supplies202-208 of FIG. 2). In accordance with an example, the power supplies202-208 of FIG. 2 can distribute 12 VDC to the tray 400. Following thisexample, the interface board can convert the 12 VDC distributed voltageto different voltage (e.g., 5 VDC), which can be provided to the server404; yet, it is to be appreciated that the claimed subject matter is notlimited to the foregoing example. Additionally or alternatively, theinterface board can provide additional regulation of the distributedvoltage if necessary. By way of yet another example, the interface boardcan allow the tray 400 to individually control power for the tray 400(e.g., separate from other trays used within a modular equipment racksystem).

Now turning to FIGS. 5-6, illustrated are isometric views of exemplarytrays that can support different server board configurations. It is tobe appreciated, however, that the claimed subject matter is not limitedto the examples shown in FIGS. 5-6. For instance, storage device(s) suchas HDDs or SSDs can be added to the exemplary trays shown in FIGS. 4-5.According to another illustration, disparate trays can include suchstorage device(s) without including a server board. Moreover, it is tobe appreciated that substantially any other type of equipment can beincluded on the trays shown in FIG. 5-6, the disparate trays thatinclude storage device(s), or separate trays.

With reference to FIG. 5, illustrated is a tray 500 that includes aserver motherboard 502 with a first form factor. Further, the tray 500includes a blind mate connector 504 at a rear edge of the tray 500. Theblind mate connector 504 is suitable for interconnecting the tray 500with a power and network distribution unit (e.g., one of the power andnetwork distribution units 114-116 of FIG. 1, the power and networkdistribution unit 200 of FIG. 2, etc.).

Turning to FIG. 6, illustrated is a tray 600 that includes a servermotherboard 602 with a second form factor. Similar to the tray 500 ofFIG. 5, the tray 600 includes a blind mate connector 604 that issuitable for interconnecting the tray 600 with a power and networkdistribution unit (e.g., one of the power and network distribution units114-116 of FIG. 1, the power and network distribution unit 200 of FIG.2, etc.). As illustrated, a width of the tray 600 is narrower than awidth of the tray 500 of FIG. 5.

Now referring to FIG. 7, illustrated is an isometric view of anotherexemplary modular equipment rack system 700 for a data center. Themodular equipment rack system 700 includes a power and networkdistribution unit 702 and a guide module 704. Similar to the power andnetwork distribution units 114-116 of FIG. 1 and the power and networkdistribution unit 200 of FIG. 2, the power and network distribution unit702 can supply power and networking to one or more trays (e.g., a tray706, etc.) attached thereto. For instance, the one or more trays can besubstantially similar to the tray 400 of FIG. 4, the tray 500 of FIG. 5,or the tray 600 of FIG. 6.

The power and network distribution unit 702 can be mountable in a rack.For example, the power and network distribution unit 702 can bemountable in a standard rack (e.g., a 19-inch rack, a 23-inch rack,24-inch rack, 28-inch rack, etc.). However, it is to be appreciated thatthe power and network distribution unit 702 can be mountable insubstantially any other type of rack (e.g., the power and networkdistribution unit 702 can be mountable in the modular equipment racksystem 100 of FIG. 1, etc.).

Moreover, the guide module 704 can be mountable in the rack. The guidemodule 704 can be mountable above or below the power and networkdistribution unit 702 in the rack. The power and network distributionunit 702 and the guide module 704 can be positioned at a distance fromeach other suitable for a size of tray(s) to be utilized therewith.Accordingly, the power and network distribution unit 702 and/or theguide module 704 can be repositioned depending upon the size of thetray(s) being employed therewith.

Further, a tray (e.g., the tray 706, etc.) can be receivable between thepower and network distribution unit 702 and the guide module 704 whenthe power and network distribution unit 702 is mounted at a firstposition in the rack and the guide module 704 is mounted at a secondposition in the rack. For instance, the first position can be above orbelow the second position in the rack. According to an illustration,tray(s) (e.g., including the tray 706) can be slid between the power andnetwork distribution unit 702 and the guide module 704. The power andnetwork distribution unit 702 and/or the guide module 704 provideguidance and support for the tray(s) (e.g., the trays can be slid intogrooves on a surface of the power and network distribution unit 702and/or the guide module 704). Additionally or alternatively, whenpositioned between the power and network distribution unit 702 and theguide module 704, the tray(s) can be attached to the power and networkdistribution unit 702 and/or the guide module 704 (e.g., using screws,clips, bolts, etc.).

The power and network distribution unit 702 can further include abackplane 708 that includes a plurality of tray connection points. Thepower and network distribution unit 702 can supply power and networkingto a tray (e.g., the tray 706, etc.) through a particular one of theplurality of tray connection points when coupled with the tray. Forinstance, the tray can include a blind mate connector (e.g., the blindmate connector 402 of FIG. 4) that couples with the particular one ofthe plurality of tray connection points of the backplane 708.

Moreover, the power and network distribution unit 702 can include one ormore power supplies, which can be substantially similar to the powersupplies 202-208 of FIG. 2. As shown in the example of FIG. 7, the powerand network distribution unit 702 can include three power supplies: apower supply 710, a power supply 712, and a power supply 714(collectively referred to as power supplies 710-714). It is to beappreciated, however, that the claimed subject matter is not so limited.A housing of the power and network distribution unit 702 can includeportions in which the power supplies 710-714 can be received.

The power and network distribution unit 702 can further include anetwork and control module 716. The network and control module 716 canprovide network distribution similar to the network switches 210-212 ofFIG. 2. Moreover, the housing of the power and network distribution unit702 can include a portion in which the network and control module 716can be received. According to another example (not shown), it iscontemplates that the power and network distribution unit 702 caninclude network switch(es) instead of the network and control module716.

FIG. 8 shows an isometric view of the power and network distributionunit 702 and the guide module 704 of FIG. 7. The power and networkdistribution unit 702 is illustrated with the power supplies 710-714 andnetwork and control module 716 removed. As illustrated in FIG. 8, thebackplane 708 of the power and network distribution unit 702 includestray connection points (including a tray connection point 802). By wayof example, the backplane 708 can include ten tray connection points,and thus, ten trays can be coupled with the power and networkdistribution unit 702; however, it is to be appreciated that thebackplane 708 is not so limited and can include substantially any numberof tray connection points.

The power and network distribution unit 702 and the guide module 704 canbe utilized in a rack to receive tray(s) without side walls. Thus, thepower and network distribution unit 702 and the guide module 704 can berepositioned within a rack with respect to each other. In comparison, aconventional chassis used with blade servers commonly includes a housingthat includes side walls which inhibit reconfiguration such that bladesof various sizes are typically unable to be used with a common housing.

Now referring to FIGS. 9-10, illustrated are isometric views of variousexemplary configurations of the power and network distribution unit 702and the guide module 704 of FIG. 7. The power and network distributionunit 702 and the guide module 704 can be separated by a variabledistance to accommodate various sizes of trays (e.g., trays withdifferent widths). As illustrated in FIG. 9, a plurality of trayssubstantially similar to the tray 500 of FIG. 5 can be received betweenthe power and network distribution unit 702 and the guide module 704.Further as shown in FIG. 10, a plurality of trays substantially similarto the tray 600 of FIG. 6 can be received between the power and networkdistribution unit 702 and the guide module 704. It is to be appreciated,however, that the claimed subject matter is not limited to the foregoingexamples shown in FIGS. 9-10.

Moreover, the power and network distribution unit 702 and/or the guidemodule 704 can be moved within a rack to accommodate various sizes oftrays. Thus, if the tray 500 of FIG. 5 is initially employed, then thepower and network distribution unit 702 and the guide module 704 can bepositioned with respect to each other as shown in FIG. 9 (e.g., thepower and network distribution unit 702 can be mounted at a firstposition in the rack and the guide module 704 can be mounted at a secondposition in the rack). Further, if the tray 600 of FIG. 6 is thereafteremployed, then the power and network distribution unit 702 and/or theguide module 704 can be repositioned (e.g., within the rack) withrespect to each other to be separated as shown in FIG. 10 (e.g., thepower and network distribution unit 702 can be reconfigured to bemounted at a third position in the rack and/or the guide module 704 canbe reconfigured to be mounted at a fourth position in the rack). Yet,the claimed subject matter is not limited to the above example.

Pursuantto another example, the power and network distribution unit 1110 caninclude the backplane 1106.

According to the example depicted in FIG. 11, the power and networkdistribution unit 1110 can include a connector 1112. Further, a LES 1114can couple with the connector 1112 of the power and network distributionunit 1110. Moreover, it is contemplated that the connector 1112 can beincluded in a power supply of the power and network distribution unit1110, and the LES 1114 can couple with the connector 1112 tointerconnect the LES 1114 and the power supply.
